Why Your Key Fob Battery Might Need Replacing
Just like your car battery, your key fob battery has a limited lifespan. Several signs indicate it might be time for a replacement:

Before you begin, gather the following:
- A new CR2025 battery: This is the type of battery used in most 2016 Mazda CX-5 key fobs.
